Patient platform, with coordination via bilateral straight-line mechanism

Abstract

A bilateral straight line mechanism that is part of a patient support mechanism.

What is claimed is: 
     
       1. A patient platform, comprising:
 a first planetary gear contained in a housing with a first scotch yoke; 
 a second planetary gear contained in a housing with a second scotch yoke; and 
 a first radiolucent laminar member coupled to the first scotch yoke and a second radiolucent laminar member coupled to the second scotch yoke, wherein the first radiolucent laminar member is coupled to the second radiolucent member and the first radiolucent laminar member and the second radiolucent laminar member support a patient platform. 
 
     
     
       2. The patient platform of  claim 1 , wherein the first radiolucent laminar member is coupled to the second radiolucent laminar member with a radiolucent connector. 
     
     
       3. The patient platform of  claim 2 , wherein the radiolucent connector is a removable radiolucent connector. 
     
     
       4. The patient platform of  claim 1 , wherein the first laminar member has a buttress on at least one side. 
     
     
       5. The patient platform of  claim 1  wherein the first scotch yoke has a total range of vertical rotation of a maximum of seventy-two degrees. 
     
     
       6. The patient platform of  claim 5  where the second scotch yoke has the same range of vertical rotation as the first scotch yoke. 
     
     
       7. The patient platform of  claim 1 , further comprising a first support that allows movement of the first scotch yoke vertically, and
 a second support that allows movement of the second scotch yoke vertically. 
 
     
     
       8. The patient platform of  claim 1 , where the first radiolucent laminar member and the second radiolucent laminar member have fiducial markers. 
     
     
       9. The patient platform of  claim 1 , where the first radiolucent laminar member and the second laminar member are set into each other. 
     
     
       10. A patient platform method for support of a patient, including:
 supporting a first planetary gear contained in a housing with a first scotch yoke; 
 supporting a second planetary gear contained in a housing with a second scotch yoke; and 
 coupling a first radiolucent laminar member attached to the first scotch yoke with a second radiolucent laminar member attached to the second scotch yoke, with a radiolucent connector. 
 
     
     
       11. The patient platform method of  claim 10 , wherein the radiolucent connector is a removable radiolucent connector. 
     
     
       12. The patient platform method of  claim 10 , includes buttressing the first laminar member with a buttress on at least one side of the first laminar member. 
     
     
       13. The patient platform method of  claim 10 , includes vertically rotating the first scotch yoke at a maximum of seventy-two degrees. 
     
     
       14. The patient platform method of  claim 13  where the second scotch yoke has the same range of vertical rotation as the first scotch yoke. 
     
     
       15. The patient platform method of  claim 10 , further includes supporting with a first support the first scotch yoke and allowing movement vertically, and
 supporting with a second support that allows movement of the second scotch yoke vertically. 
 
     
     
       16. The patient platform method of  claim 10 , includes marking the first radiolucent laminar member and the second radiolucent laminar member with fiducial markers. 
     
     
       17. The patient platform method of  claim 10 , includes setting into the first radiolucent laminar member the second radiolucent laminar member.
